    摘要: The present invention has an object to provide an active-matrix liquid crystal display device that realizes the improvement in productivity as well as in yield. In the present invention, a laminate film comprising the conductive film comprising metallic material and the second amorphous semiconductor film containing an impurity element of one conductivity type and the amorphous semiconductor film is selectively etched with the same etching gas to form a side edge of the first amorphous semiconductor film 1001 into a taper shape. Thereby, a coverage problem of a pixel electrode 1003 can be solved and an inverse stagger type TFT can be completed with three photomask.

    摘要: It is an object of the present invention to provide a manufacturing method of semiconductor device whereby the number of processes is decreased due to simultaneously forming a contact hole in a lamination film of different material and film thickness (inorganic insulating film and organic resin film) by conducting etching once. By setting the selective ratio of dry etching (etching rate of organic resin film 503/etching rate of inorganic insulating film 502 containing nitrogen) from 1.6 to 2.9, preferably 1.9, the shape and the size of the contact holes to be formed even in a film of different material and film thickness can be nearly the same in both of the contact holes.
